INDEX DEvIcE.

Application led December 20, 1924. Serial No. 757,187. i

This invention relates to card indexes and more particularlyto card indexes of the type in which a plurality of cards are mounted in an upright frame in overlapping relationship so that the lower margins of the cards are visible and so that the cards Fig. 1 is a front view of an index unit constructed in 'accordance with the present invention;

Fig. 2 is a fragmentary front view of the index unit with the on order moved Fig. 3 is an enlarged section substantially ig. 1; and Fig. 4 is a front View of the order slip. In the illustratedembodiment of the invention the index unit comprises a holder 1 of cardboard or relatively stift' paper on the upper margin of 'which is flexibly connected a supporting 'rail 2 which projects beyond the sides of the holder and is adapted to extend into channels in a suitable supporting frame for holding the unit in place.

Detachably connected to, the holder 1 is a sheet 3 which may be of relativel flexible paper or other suitable materia preferably smaller than the holder.

Enclosmg the lower margins of the holder 1 and sheet 3 and connected to the holder as by staples 4 is a sheath 5 of transparent sheet material such as sheet cellulold which may be formed of a sheet of such material folded upon itself along one longitudinal vmargin to fbrm front and rear' walls whlch are yieldingly urged toward each other owing to the resiliency of the mate-v rial. The corners of the sheet 3 remote from the sheath 5 extend through diagonal' slits 6 in the holder'lso that in this manner allel relationship tothe free edge ofthe vfront of the sheath 5 .is anopening or slit 7.

slip reand is Also provided in the sheet 3 is an aperture `8\ which is preferably positioned between the slit 7. and the lower margin of the sheet to be visible through the sheath 5. As indicated in Fig. 1 a slip 9 is formed with cutaway or bevelled lower edges 10 to permit -it to readily be inserted through the slit 7 and extend between the sheet 3 and holder 1. On the slip 9 adjacent .the lower marginl thereof and arranged to show though the aperture 8 when the slip is in place is 'an area v11 which may be colored differently from the holder 1. It willn readily be understood thatwhen the slip is in place in the index unit this will'be visibly indicated means of a portion of the colored area 11 showing therethrough', and when removedv from the unit this also will be indicated by a different color showing through the aperture. vSuch signal is particularly advantageous when a number` of units are arranged in `spaced overlapping relationship; because it becomes unnecessary to swing one unit relatively to adjacent unitsto determine the presence or absence of the slip 9.

An index unit as abovedescribed may be used in a variety of situations but is shown as adapted for keepinga detailed account of sales made froma certain stock so that'at a. glance a user of the index may determinev the sales progressl in diiferent lines so that a new stock may be ordered in proper time and the sales policy adjusted according to were 18 articles of a certain character in` l itially in s tock and the signal 13 serves to indicate' the number of articles which have been sold from Vthe initial stock which in l adjathe present case is 8.- 'The difference between the two indications, i. e. between' 18 and `8 or 10 indicates the number of articles remaining fromthe initial stock which. are

7o through the aperture 8 in the .sheet `3 by pose the slip 9 may have such indicia as Date of order, Order No, Quantity etc., and after having been filled out by A the buyer it may be inserted in place in the index unit, the presence therein being indicated as above pointed out by the diderent -color showing through the aperture 8 so that this will be indicated readily even to the most casual observer. As soon as the order is lillcd .the signal 14ev is moved accordingly and the slip 9 removed from the unit, the absence of the slip also being indicated by a different color showing through the aperture 8.

Although I have shown and described a device which at the present time is believed Vto be the best form, it will be understood that numerous changes lin details of" construction, arrangement andselection of material may be made without departing from the spirit of the invention, especially as deiined by the appended claims. It is further to be understood that I do not wish to limit the invention to the use hereinbeioreY `described "as it may be used to advantage,

in numerous other situations. It .is to be understood that the term colors throughout is used in a broad sense to connote contrasting hues or shades whether actually colored or black, white, gray, etc.

1. An index device comprising a sheet having a slit adjacent and extending sub.-

. stantially parallel to 'thel lower margin j thereof, and having an aperture between said slit and said lower margin, and a slip extending'through said slit and having a colored `area visible through said aperture, thereby to indicate the presence of said slip.

2. An index device comprising a holder, a sheath of transparent sheet material enclosing a margin of said holder to forma .pocket therewith, a sheet in said pocket having an opening adjacent to said sheath, and

a slip having a portion extending into said pocket between said sheet and holder with a portion projecting through said opening.

3..An index device comprising a holder, a sheath of transparent sheet material enclosing a margin of said holder to form a pocket therewith, a sheet in said pocket having a slit adjacent said sheath and extending substantially longitudinally thereof, and a slip having a portion=extending through said slit between said holder and sheet and another portion extending outside of said slit.

4.' An index device comprising a holder, a sheath of transparent sheet material enclosing a margin of saidholder to form a pocket therewith, a sheet extending uinto said pocket and having an opening and also having an aperture in the region of said sheath, a slip extending through said opening between said holder and sheet, and visible through said aperture to indicate the presence or absence of the slip. n

'5. An index device comprising, a holder,

a sheath o transparentl sheet material enclosing the lower margin of said holder to form a pocket therewith, a removable sheet in said pocket, said sheet having a slit extending alongside said sheath and also having an aperture adjacent the lower margin zusv thereof, a slip extending through said slit v between ysaid holder and sheet, and a colored area on said slip arranged to be visible through said aperture therebyxto indi- 'cate the presence of said sli Signed by-me at New Yor N.A Y.,this 15th day of December 1924.
